LOS ANGELES (Reuters) - Actor Charlie Sheen on Wednesday went to a Los Angeles hospital where his wife was being treated for a high fever, boosting reports that the couple want to reconcile after a violent Christmas Day quarrel.

Mueller's lawyer told TMZ she had been admitted to the intensive care unit with an infection from dental surgery, but was expected to be released later on Wednesday.

Sheen, 44, was arrested on Christmas Day in the ski resort of Aspen, Colorado, after Mueller told police he pulled a knife on her during an argument and threatened to have her killed.

No formal charges have been filed and Mueller is widely reported to want the case dropped.

"She wants to reconcile and get on with her life with Charlie and the babies," Mueller's lawyer Yale Galanter was quoted as telling the New York Daily News on Wednesday.

Sheen and his third wife, who married in 2008 and have 9 month-old twin boys, are due back in court in Aspen on Friday, when Sheen will ask for the lifting of a restraining order that prohibits him from having contact with his wife.

Mueller's lawyers have told the court that she also wants the order removed.
